Narrative:

I was with a student on an IFR training/business flight. He is an instrument student transitioning to glass cockpit flying. We were about 2 hours into the flight and he had been flying the entire time. The WX at ekx; our destination; was IFR. ATC cleared us for the VOR-a approach to ekx and he became confused in trying to set up the approach. I then loaded and activated the approach and it became obvious; at the last min; that I would have to fly the approach. Without proper time to brief it myself; I crossed the new hope VOR at 2500 ft MSL and; rather than maintaining 2500 ft to syndi; the FAF; then descending to 1700 ft to mayho; I misread the approach plate and descended to 1700 ft between new hope VOR and syndi. Without proper time to prepare; and jumping in cold; I should have asked ATC to be vectored around for another attempt. Even though the student had done extremely well up to this point; as in previous lessons; I should not have allowed myself to get complacent and should have fully briefed the approach as if I would be flying it. Lesson learned.

Title: INSTRUMENT INSTRUCTOR HAS ALT DEV ON IAP WHEN FORCED TO TAKE OVER FROM DISORIENTED STUDENT.

Narrative: I WAS WITH A STUDENT ON AN IFR TRAINING/BUSINESS FLT. HE IS AN INST STUDENT TRANSITIONING TO GLASS COCKPIT FLYING. WE WERE ABOUT 2 HRS INTO THE FLT AND HE HAD BEEN FLYING THE ENTIRE TIME. THE WX AT EKX; OUR DEST; WAS IFR. ATC CLRED US FOR THE VOR-A APCH TO EKX AND HE BECAME CONFUSED IN TRYING TO SET UP THE APCH. I THEN LOADED AND ACTIVATED THE APCH AND IT BECAME OBVIOUS; AT THE LAST MIN; THAT I WOULD HAVE TO FLY THE APCH. WITHOUT PROPER TIME TO BRIEF IT MYSELF; I CROSSED THE NEW HOPE VOR AT 2500 FT MSL AND; RATHER THAN MAINTAINING 2500 FT TO SYNDI; THE FAF; THEN DSNDING TO 1700 FT TO MAYHO; I MISREAD THE APCH PLATE AND DSNDED TO 1700 FT BTWN NEW HOPE VOR AND SYNDI. WITHOUT PROPER TIME TO PREPARE; AND JUMPING IN COLD; I SHOULD HAVE ASKED ATC TO BE VECTORED AROUND FOR ANOTHER ATTEMPT. EVEN THOUGH THE STUDENT HAD DONE EXTREMELY WELL UP TO THIS POINT; AS IN PREVIOUS LESSONS; I SHOULD NOT HAVE ALLOWED MYSELF TO GET COMPLACENT AND SHOULD HAVE FULLY BRIEFED THE APCH AS IF I WOULD BE FLYING IT. LESSON LEARNED.
